If they are just providing a whitelist of permitted system calls, then it 
should not be subject to the known issues with systrace(4) as those are 
related to parsing system call arguments.

It also looks from some mailing lists that OpenBSD is looking at porting
Capsicum to OpenBSD which should provide an even richer sandbox environment.
